The THT-ZT transformer neutral grounding resistor cabinets are
applicable to the transformer neutral points of 6~35KV AC power
grids to achieve the neutral point grounding via resistor.
2, Product feature
- Incase resistor processing adopts special high resistance alloy
resistors, molding, grid structure, argon arc welding, the joint
quality, surface smooth, neat; the grid structure (figure A) and Up
and down modular installation, together constitute the inside and
outside air from the circulating cooling system (figure B), To
ensure the resistor sufficient heat dissipation.
- Insulation parts selectehigh quality phlogopite gasket that can assure resistor with good
insulation and mechanical locking strength; Traditional porcelain
insulation parts is worse than mica gasket, including easy damaged
in the installation, use and transportation
2)other electrical accessories in cabinet
- Current transformer which adopts famous brand CT product is
- Neutral intelligent control system, can monitor the neutral
unbalance current,the temperature change of resistor, resistance
ark, and record the grounding current, grounding time, temperature
change of resistor, resistance , grounding number, and provide
- Temperature and humidity heater which control set value by
adjusting the temperature and humidity controller, start-up heater
heating and destruction of condensing fog cabinet, in order to
prevent condensation fog inside.
- It adopt stationary type structure that each component combination
step by step . the bottom of cabinet adopt that national standard
box ironarewelded forming ,other components all adopt Sheet Metal machining
technology that cause no stress accumulation between components .
it ensure the integrity and fastness of cabinet
- Speaking from the protection degree of the cabinet, the protection
degree of cabinet can be made from IP00 to IP55 that suitable to
site environmental as per the cabinet installation place . Adopting
special built-in type structure for the door,outdoor cabinet that
the top are designed with rainhat . the cabinet inside has special
Letter of the ventilation and outside has Scales pore structure
design,it ensure that resistor inside ark can be sufficient heat
- The nameplate adopt theart ofstainless steelengraving whichcause the nameplate to mark clearly wearproof,easy Clean,durable in use.
